Family dinners in the MDR. Yeah, the food is good not the best ever, but it's a treat. First, we never have to debate "where do we eat tonight" or "what should I cook?" Second, we never have to look at price or worry that we might not like what we order. Third, we know DD will get good service just like the adults. Fourth, I don't have to worry about dishes, getting anyone drink refills, etc.
Only on a cruise do we get so many nights of that experience all in a row.
